Gillette has upped the ante in the razor wars. The new Gillette Fusion ($8) steps over the 4-blade Schick Quattro with its astounding 5-blade surface. The new razor also has a single trimming blade on the back for sideburns and such, and the blades on the Fusion are spaced 30 percent closer than Gillette's current MACH3Turbo system for less irritation. The Gillette Fusion Power ($9) has an on-board micro-chip that "optimizes the performance of the razor by regulating the voltage and frequency," as well as a low-battery indicator light and an automatic shut-off feature.
